Description
Technical Field
The invention belongs to mining machinery, and particularly relates to an ore crusher.
Background
The jaw crusher is commonly called as jaw crusher, also called as old tiger mouth, and is a crusher which is characterized in that a crushing chamber is formed by two jaw plates of a movable jaw and a static jaw, simulates the movement of two jaws of an animal to complete material crushing operation, and is widely applied to crushing various ores and large materials in the industries of mine smelting, building materials, highways, railways, water conservancy, chemical engineering and the like, wherein the highest compressive strength of the crushed materials is 320 Mpa.
The Jaw Crusher has the foreign name of Jaw Crusher which is called Jaw Crusher and old tiger mouth, the most commonly used ore crushers are divided into single-pendulum Jaw Crusher and compound-pendulum Jaw Crusher, the commonly used Jaw Crusher has two types of double-toggle plates and single-toggle plate, the former only swings in a simple circular arc when working, and the latter also swings in a circular arc and moves up and down.
The technical levels of domestic jaw crusher manufacturers are very different, the products of a few manufacturers are close to the world advanced level, the difference between the products of most manufacturers and the world advanced level is larger, the proportion of a jaw crusher frame to the whole machine mass is very large, wherein a casting frame accounts for 50 percent, a welding frame accounts for 30 percent, the jaw crushers at home and abroad are all welding frames, even a movable jaw adopts a welding structure, the jaw crusher adopts the welding frame as the development direction, the unreasonable design examples of the domestic jaw crusher frame structure are many, and the reason is that reinforcing ribs are not arranged according to the actual stress condition of the crusher,
in recent years, with the increase of mining specific gravity of strip mines and the adoption of large excavators and large mining automobiles, the lump size of ore transported to a crushing workshop of the strip mine reaches 1.5 ~ 2.0.0 m, meanwhile, as the grade of raw ore is gradually reduced, the mining amount and the crushing amount of the raw ore are greatly increased to maintain the original production capacity of a concentrating mill, so that the jaw crusher is developing towards a large size direction, and at present, the largest size jaw crusher manufactured abroad is simply swung to 3000 multiplied by 2100 mm, the lump size of ore feeding is 1800 mm, the production capacity is 1100 tons/ton.h, the swing is 2100 multiplied by 1670 mm, and the production capacity is 3000 tons/ton.h when the ore discharge opening is 355 mm.
With the appearance of impact-resistant large-sized rolling bearings, the trend of replacing simple pendulum crushers with compound pendulum jaw crushers is at home and abroad, because under the same conditions, the production capacity of the compound pendulum jaw crushers is improved by 30% compared with that of the simple pendulum crushers, and the weight of the compound pendulum jaw crushers is reduced by ~ 30% compared with that of the simple pendulum crushers when the production capacities of the compound pendulum jaw crushers and the simple pendulum jaw crushers are the same.
It should be seen that in recent years, due to the improvement of the material of large rolling bearings in China and the requirement of underground coarse crushing equipment, the compound pendulum jaw crusher also has a trend of large-scale development, a 900 × 1200 compound pendulum crusher is trial-manufactured at present, and along with the large-scale equipment specification, a new mechanism is inevitably adopted for an adjusting device and a safety device of a common jaw crusher, so that another trend of the current jaw crusher development is that a hydraulic adjusting mechanism is adopted for a mine discharge port, so that the hydraulic adjusting mechanism is simple, convenient and rapid, and can be adjusted at any time in work as required; meanwhile, the overload safety device of the machine adopts a hydraulic mechanism, so that the safety and the reliability are achieved, the thrust plate is not damaged, the machine can be immediately restored to work after the fault is eliminated, the hydraulic jaw crusher is vigorously developed at home and abroad, the 900X 1200 hydraulic simple swing jaw crusher is already produced in China, and is put into production and use in Laiwu iron ore and Roots iron ore, the production practice proves that the safety mechanism and the adjusting mechanism of the hydraulic jaw crusher achieve the purposes of safety and convenience in adjustment, the condition is good, and the hydraulic jaw crusher is deeply welcomed by post workers.
In the aspect of improving the crushing efficiency of the jaw crusher, the structure of the original equipment is locally improved, for example, the height of a crushing chamber is increased, and the production capacity is improved; the ore discharge port is reduced, and the crushing ratio is increased; the swing speed of the movable jaw is increased to improve the production capacity of equipment and improve the product quality, and at present, crushers with novel structures, such as an impact jaw crusher, a jaw crusher with double movable jaws, a hydraulically-driven jaw crusher and the like, are researched and tested in various countries.
The working part of the jaw crusher is two jaws, one is a fixed jaw which is vertically fixed on the front wall of the crusher body or slightly outwards inclined at the upper end, and the other is a movable jaw which is inclined at the position and forms a crushing chamber with the fixed jaw. The movable jaw plate is opposite to the fixed jaw plate to do periodic reciprocating motion, and the movable jaw plate is separated from the fixed jaw plate and is close to the fixed jaw plate, when the movable jaw plate is separated from the fixed jaw plate, the material enters the crushing chamber, and the finished product is discharged from the lower part; when approaching, the material between the two jaws is squeezed, bent and split to be broken.
Jaw crushers can be divided into a simple swing type jaw crusher, a complex swing type jaw crusher and a comprehensive swing type jaw crusher according to different swing modes of a movable jaw plate.
In the case of jaw crushers, although of different types, their operating principle is basically similar, except that the path of movement of the movable jaw differs, in general, when the movable jaw is moved back and forth periodically about the suspension axis against the fixed jaw, but when the movable jaw approaches the fixed jaw, the ore present between the jaws is crushed by the combined action of crushing, splitting and bending; when the movable jaw plate leaves the fixed jaw plate, the crushed ore is discharged through an ore discharge port of the crusher under the action of gravity.
Simple pendulum jaw principle: the movable jaw is hung on the mandrel and can swing left and right, when the eccentric shaft rotates, the connecting rod reciprocates up and down to drive the two thrust plates to reciprocate, thereby pushing the movable jaw to do left-right reciprocating motion to realize crushing and discharging, the crusher adopts a crank double-connecting rod mechanism, although the movable jaw is subjected to great crushing counter force, the eccentric shaft and the connecting rod are not subjected to great stress, so that large and medium sized machines are often made in industry for crushing hard materials, and, in addition, when such crushers are operated, the motion track of each point on the movable jaw is an arc with the mandrel as the center, the radius of the arc is equal to the distance from the point to the axis, the arc at the upper end is small, the arc at the lower end is large, the crushing efficiency is low, the crushing ratio is generally 3-6, the simple swing jaw crusher is called as a simple swing jaw crusher due to simple motion trail, the simple swing jaw crusher has compact and simple structure, and the stress of transmission parts such as an eccentric shaft and the like is smaller; because the vertical displacement of the movable jaw is small, the materials are less in excessive crushing during processing, and the abrasion of the jaw plate of the movable jaw is small.
The principle of the compound pendulum type jaw crusher is as follows: the upper end of the movable jaw is directly hung on the eccentric shaft and is used as a connecting rod of the crank connecting rod mechanism, the connecting rod is directly driven by the eccentricity of the eccentric shaft, and the lower end of the movable jaw is hinged with a thrust plate and is supported on the rear wall of the rack. When the eccentric shaft rotates, the motion trail of each point on the movable jaw is gradually changed into an ellipse from the circumferential line of the suspension point downwards, the ellipse is deviated from the lower part of the movable jaw until the trail of the connection point of the lower part and the thrust plate is an arc line, and the machine is called a complex swing type jaw crusher because the motion trail of each point on the movable jaw is complex.
Compared with a simple pendulum type, the compound pendulum type jaw crusher has the advantages that: the weight is lighter, the components are fewer, the structure is more compact, the filling degree in the crushing cavity is better, the loaded material blocks are uniformly crushed, the lower end of the movable jaw is added to forcibly push out a finished product for discharging, so the productivity is higher and is 20-30% higher than that of a simple swing jaw crusher with the same specification, the material blocks have larger up-and-down rolling motion at the lower part of the movable jaw and are easily discharged in a cubic shape, and in the design, the crushing plates of the movable jaw and the fixed jaw should have tooth peaks to be opposite to tooth valleys, so that the crushing plate has a bending effect on the material in the crushing process, the material is easier to crush, and in order to prolong the service life of the crushing plates, the crushing plates of the medium-sized and small-sized crusher are designed into vertically symmetrical shapes and can be used by adjusting heads after the lower part; the crushing plates of the large jaw crusher are designed into a plurality of mutually symmetrical blocks so as to be conveniently exchanged for use after being worn, white cast iron can be selected as the material of the crushing plates, the white cast iron has higher hardness, better wear resistance, easy source and low price and has the defects of brittleness, easy breakage and short service life, manganese steel containing more than 12 percent of manganese is better used for prolonging the service life of the crushing plates, ZGMn13 is commonly used, the toughness of the manganese steel is better, although the hardness is not high and is about 210HB, but the operation of water toughening treatment is basically the same as quenching, namely the cast manganese steel crushing plates are heated to 1000-1100 ℃ and then are rapidly cooled in water because the manganese steel crushing plates have the characteristic of cold work hardening and can be continuously strengthened under the pressure effect, so the manganese steel crushing plates are continuously worn and strengthened in work until being worn to be abandoned, the manganese steel crushing plates are cast and then are subjected to water toughening treatment, and the operation of the water toughening treatment is basically the same as the quenching, the homogeneous metallographic structure can be obtained after the water toughening treatment, and the metallographic structure is fixed, so that the performance deterioration caused by the natural phase change in use is avoided, the manganese steel has the defect of high price, but compared with white cast iron, the ZGMn13 has the advantages of long service life and low cost in the aspects of service life, cost and the like.
Disclosure of Invention
